HT enabled?

sentme_mail · Jan 2, 2003

hi,
how do i know that Hyper threading is enabled on my P4 cpu??
thanks

1) You have an intel P4 3.06Ghz.
2) Your mobo supports HT and the BIOS shows "hyperthreading enabled".
3) You run WinXP.

Yeah kind of weird. I would like to see 2K support myself (am running it), but this is the word straight from the Man.
